Title
(EN) AIRCRAFT RINSE SYSTEM
(FR) SYSTEME DE RINÇAGE POUR AERONEF
Abstract
(EN)
A method and apparatus for separating particles and dissolved matter from a fluid stream incorporated in an aircraft rinse system. The present invention includes a first pressure source which transports collected rinse fluid into a separator annulus with a filter element disposed therein. The untreated fluid is placed under appropriate pressure sufficient to produce turbulent flow, increased particle kinetics and/or cavitation physics allowing the desired fluid to penetrate and pass into and through the filter media. The filtered fluid is then transported to a collection tank. The contaminant particulate matter retained on the exterior of the filter media may be removed by the instantenous reverse pressurization of the separator annulus by a second pressure source thereby removing the contaminant particles away from contact with the filter media, and which may then be transported to a waste collection tank or a concentrator for further treatment. The treated rinse fluid is thus recycled for use in the aircraft rinse system.

Cette invention concerne un procédé et un dispositif permettant de séparer des particules et de la matière dissoute d'un flux liquide intégré dans un système de rinçage pour aéronef. Le système comprend une première source de pression assurant le transport du liquide de rinçage recueilli dans un anneau de séparation dans lequel est disposé un élément filtrant. Le liquide non traité est soumis à une pression suffisante pour produire un écoulement turbulent, l'accroissement cinétique des particules et/ou les règles physiques de cavitation permettant au liquide de pénétrer dans le support filtrant et de le traverser. Le liquide filtré est ensuite dirigé vers un réservoir collecteur. La matière particulaire contaminante retenue sur la paroi extérieure du filtre peut être détachée par pressurisation inverse instantanée de l'anneau séparateur provoquée par une seconde source de pression, ce qui a pour effet de détacher les particules du filtre, lesquelles peuvent ensuite être évacuées dans un réservoir collecteur de déchets ou un concentrateur pour traitement complémentaire. Le liquide de rinçage traité peut ainsi être recyclé et utilisé dans le système de rinçage de l'aéronef.
